I am using boost::format (v0.7) happily for some time.
Recently I tried compiling the example program, and g++ (compiled from a
recent 3.1 cvs ) refused because of some copy ctors of members of basic_stringstream
Is there a reason why parameters are copied instead of passed by
reference in those ctors :
basic_format(const charT* ca, A a);
(idem for all multi-argument ctors..)
Because, when A is boost::format, as needed in
std::cout << format("The Truth is %1", format("%1 != %2", 1, 2)) <<
that implies copying a basic_stringstream, and that is not allowed.
using the following ctors, the test program compiled and ran correctly :
basic_format(const charT* ca, const A& a);
and I humbly think this is the way it should be..
